2022-08-12fec: Fix timer capture timing in `fec_ptp_enable_pps()`Csókás Bence1-5/+1
Code reimplements functionality already in `fec_ptp_read()`, but misses check for FEC_QUIRK_BUG_CAPTURE. Replace with function call.

We need to make sure (at build time) that struct io_cmd_data is not casted to a structure that's larger.

2022-08-12fs: don't randomize struct kiocb fieldsKeith Busch1-5/+0
This is a size sensitive structure and randomizing can introduce extra padding that breaks io_uring's fixed size expectations. There are few fields here as it is, half of which need a fixed order to optimally pack, so the randomization isn't providing much.

Fix deadlock that occurs when iavf interface is a part of failover configuration. 1. Mutex crit_lock is taken at the beginning of iavf_watchdog_task() 2. Function iavf_init_config_adapter() is called when adapter state is __IAVF_INIT_CONFIG_ADAPTER 3. iavf_init_config_adapter() calls register_netdevice() that emits NETDEV_REGISTER event 4. Notifier function failover_event() then calls net_failover_slave_register() that calls dev_open() 5. dev_open() calls iavf_open() that tries to take crit_lock in end-less loop Stack trace: ...

2022-08-12iavf: Fix reset error handlingPrzemyslaw Patynowski1-3/+6
Do not call iavf_close in iavf_reset_task error handling. Doing so can lead to double call of napi_disable, which can lead to deadlock there. Removing VF would lead to iavf_remove task being stuck, because it requires crit_lock, which is held by iavf_close. Call iavf_disable_vf if reset fail, so that driver will clean up remaining invalid resources. During rapid VF resets, HW can fail to setup VF mailbox. Wrong error handling can lead to iavf_remove being stuck with: [ 5218.999087] iavf 0000:82:01.0: Failed to init adminq: -53 ...

2022-08-12iavf: Fix NULL pointer dereference in iavf_get_link_ksettingsPrzemyslaw Patynowski1-1/+1
Fix possible NULL pointer dereference, due to freeing of adapter->vf_res in iavf_init_get_resources. Previous commit introduced a regression, where receiving IAVF_ERR_ADMIN_QUEUE_NO_WORK from iavf_get_vf_config would free adapter->vf_res. However, netdev is still registered, so ethtool_ops can be called. Calling iavf_get_link_ksettings with no vf_res, will result with: [ 9385.242676] BUG: kernel NULL pointer dereference, address: 0000000000000008 [ 9385.242683] #PF: supervisor read access in kernel mode [ 9385.242686] #PF: error_code(0x0000) - not-present page [ 9385.242690] PGD 0 P4D 0 [ 9385.242696] Oops: 0000 [#1] PREEMPT SMP DEBUG_PAGEALLOC PTI [ 9385.242701] CPU: 6 PID: 3217 Comm: pmdalinux Kdump: loaded Tainted: G S E 5.18.0-04958-ga54ce3703613-dirty #1 [ 9385.242708] Hardware name: Dell Inc.

Sstc extension allows the guest to program the vstimecmp CSR directly instead of making an SBI call to the hypervisor to program the next event. The timer interrupt is also directly injected to the guest by the hardware in this case. To maintain backward compatibility, the hypervisors also update the vstimecmp in an SBI set_time call if the hardware supports it. Thus, the older kernels in guest also take advantage of the sstc extension.

Commit 6f8191fdf41d ("block: simplify disk shutdown") removed the call to blk_get_queue() during gendisk allocation but missed to remove the corresponding cleanup code blk_put_queue() for it. Thus, if the gendisk allocation fails, the request_queue refcount gets decremented and reaches 0, causing blk_mq_release() to be called with a hctx still alive.

The issue happens on some error handling paths. When the function fails to grab the object `xprt`, it simply returns 0, forgetting to decrease the reference count of another object `xps`, which is increased by rpc_sysfs_xprt_kobj_get_xprt_switch(), causing refcount leaks. Also, the function forgets to check whether `xps` is valid before using it, which may result in NULL-dereferencing issues. Fix it by adding proper error handling code when either `xprt` or `xps` is NULL.

This code tries to store -EFAULT in an unsigned int. The xenbus_file_read() function returns type ssize_t so the negative value is returned as a positive value to the user. This change forces another change to the min() macro. Originally, the min() macro used "unsigned" type which checkpatch complains about. Also unsigned type would break if "len" were not capped at MAX_RW_COUNT. Use size_t for the min(). (No effect on runtime for the min_t() change).

2022-08-12xen-blkfront: Apply 'feature_persistent' parameter when connectSeongJae Park2-4/+2
In some use cases[1], the backend is created while the frontend doesn't support the persistent grants feature, but later the frontend can be changed to support the feature and reconnect. In the past, 'blkback' enabled the persistent grants feature since it unconditionally checked if frontend supports the persistent grants feature for every connect ('connect_ring()') and decided whether it should use persistent grans or not. However, commit aac8a70db24b ("xen-blkback: add a parameter for disabling of persistent grants") has mistakenly changed the behavior. It made the frontend feature support check to not be repeated once it shown the 'feature_persistent' as 'false', or the frontend doesn't support persistent grants. Similar behavioral change has made on 'blkfront' by commit 74a852479c68 ("xen-blkfront: add a parameter for disabling of persistent grants"). This commit changes the behavior of the parameter to make effect for every connect, so that the previous behavior of 'blkfront' can be restored.
